What Does the E22 Error Code Mean?

The E22 error occurs when water remains in the bottom of your dishwasher after a cleaning cycle. This is usually a sign of a drainage problem, meaning water isn’t flowing out of the machine properly. If you see this code, your dishwasher is essentially alerting you to an issue that needs attention.

Common Causes: Clogs and Blockages

In most cases, the E22 error is caused by a clogged filter. Over time, food particles, grease, and debris can build up in the filter, restricting water flow. Other potential culprits include a blocked drain hose, a jammed drain pump, or even a buildup in the spray arms.

How to Fix the E22 Error Code

Step 1: Clean the Filter

The filter is usually the main offender. Here are 4 steps on how to clean the Bosch dishwasher filter:

1. Locate the Filter: The filter is typically at the bottom of the dishwasher, under the lower spray arm.
2. Remove the Filter: Twist or pull it out, depending on your dishwasher model.
3. Clean the Filter: Rinse the filter under running water and use a soft brush to remove stubborn debris.
4. Reinstall the Filter: Place the clean filter back into position, ensuring it’s securely fitted.

Step 2: Check the Drain Hose

Inspect the drain hose for any kinks, blockages, or improper installation. A crushed or bent hose can prevent proper water flow. Disconnect it if necessary and flush it out with water to clear any clogs.

Step 3: Inspect the Drain Pump

The drain pump can sometimes become jammed when small objects, such as glass shards or food bits, bypass the filter. Check for obstructions and carefully remove them.

Step 4: Clean the Spray Arms

Clogged spray arms can affect water flow and cause drainage issues. Remove the arms and clear the holes with a thin wire or needle.

Step 5: Reset the Dishwasher

Sometimes, resetting the system can resolve the error. Disconnect the dishwasher from power by unplugging it or switching off the circuit breaker for about a minute, then reconnect.

When the Problem Persists

If you’ve gone through these steps and the E22 error still won’t disappear, it’s time to dig deeper:

• Inspect the Valve: Check for blockages or buildup in the water inlet valve and connecting hoses.
• Check Household Plumbing: A slow-draining sink or clogged garbage disposal can affect your dishwasher’s drainage.
• Call a Professional: If all else fails, the issue could involve the control board or internal wiring, which requires a technician’s expertise.

Preventing Future E22 Errors

Regular maintenance can reduce the chances of the E22 error occurring again. Here are some tips:

• Clean the Filter Regularly: Make it a habit to rinse the filter at least once a month.
• Use a Dishwasher Cleaner: Run a cleaning cycle with a commercial dishwasher cleaner to remove grease and buildup.
• Rinse Dishes Before Loading: Scrape off food debris before placing dishes in the dishwasher.
• Check for Hard Water Deposits: If your city or town has hard water, consider using a water softener or a product designed to prevent limescale.

Conclusion: Keep Your Dishwasher Draining Smoothly

Regular maintenance and the troubleshooting tips outlined here allow you to keep your dishwasher running smoothly and avoid future disruptions.
